Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

open access: yesJournal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Genome Expansion of ZPB1(a) and ZPC1(a) in Basal Species or Liver Expression of ZPB1a and ZPC1aa in Advanced Species, Two Different Strategies to Ensure Sufficient ZP Synthesis in Teleosts

open access: yesIntegrative Zoology, EarlyView.
We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

Molecular signature of selective microRNAs in Cyprinus carpio (Linnaeus 1758):a computational approach [PDF]

open access: yesExRNA, 2019
MicroRNAs (miRNAs) are small single stranded non-coding RNAs that performed significant role in post-transcriptional regulation of target gene product. They are typically conserved among the organisms and also involved in multiple biological processes by

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

open access: yesIntegrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Using Eye Lens Stable Isotopes to Identify the Rearing Origin of Fall Age‐0 Walleye (Sander vitreus)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Isotope values in fish eye lenses may be useful in differentiating rearing origins. We compared eye lens isotopic values of fall fingerling age‐0 walleye (Sander vitreus) reared in a hatchery pond, a recirculating aquaculture system (RAS), and a natural lake. Using 10 fish per rearing source, we delaminated layers from one eye lens per fish to

Genetic Diversity and Impacts of Stocking on Cyprinus carpio Populations in Türkiye: Insights From Mitochondrial, Nuclear, and Microsatellite Markers

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Understanding genetic diversity and population structure is essential for the sustainable management of widely stocked freshwater species such as common carp (Cyprinus carpio). In this study, we conducted a comprehensive genetic assessment of C.

Using Long‐Term Monitoring Data to Assess Temporal Patterns in Fish Community Assemblages in Florida Lakes

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT In an effort to increase the relevancy of fish community data for management, we used fish community data to conduct a statewide assessment of Florida's freshwater fisheries resources and compare the relationships between environmental factors and freshwater fish communities over time.

Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.
